Read the Description

Always make certain you read the description of a data set before searching. This allows you to see whether or not it includes the information you need.

The Family Search site includes some Ohio Tax records. I was excited as both my wife and I have early Ohio ancestors. Unfortunately at the time I visited the site, only a few counties were included. They will add more, but READING what areas are included before I search a database saves me time if the locations I need are not yet included.
